5. Efficiency
Efficiency is how effectively the wind energy is converted to electrical energy.
P = 0.5 x rho x A x V3
P = 0.5 x rho x A x Cp x V3 x Ng x Nb
Ng = efficiency = 38%

6. Design Issues
Out first windmill idea was a turbine that rolled parallel to the ground but was ineffective at catching wind
Our first generator idea was having the magnet spin close to a nail with coils wrapped around it

7. Conclusion Our windmill satisfies all the requirements for the project
It generates approximately 1.5 volts and satisfies all design and price limitation requirements
Other than preliminary design issues everything worked according to plan
